[PATCH] D62311: [LV] Inform about exactly reason of loop illegality

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

Thanks for adding the test. I think it would be easiest to move this along if you would split off the 2 changes in llvm/lib/Transforms/Vectorize/LoopVectorize.cpp while waiting on additional feedback for those.



================
Comment at: llvm/test/Transforms/LoopVectorize/legal_loop_config.ll:1
+; RUN: opt < %s -loop-vectorize -debug-only=loop-vectorize -S -o /dev/null 2>&1 | FileCheck %s
+; REQUIRES: asserts
----------------
I think -disable-output would be slightly better than -o /dev/null.
